If I understand things correctly, this has to do how process information are 
managed in the kernel: they are kept in a separate "address space" to which 
the process has no access once it is running (the only time this is possible 
is during startup via the appropriate parameter to one of the exec(2) system 
calls). Therefore, the process cannot alter its name that is displayed with 
ps/top/whatever (there's no "setproctitle()" or aequivalent in Solaris right 
now).

As you noted, the difference lies in the way an application is started: It is 
my understanding that (in order to increase startup speed by eliminating the 
dynamic link phase) some KDE applications can be started by asking the 
initial "kdeinit" process to fork(2) off a child instead of running the 
binary directly; konqueror is an example for the first case (check the 
"Exec=" line in the konqueror.desktop file) whereas "kmail" ist started as an 
"ordinary binary" which is why only in this case there is displayed a useful 
"process name" on Solaris systems.

Hope this helps,

	Torsten
